ABSTRACT:
To increase the efficiency of a push-pull saturation converter, a choke is introduced in a common emitter circuit of switching transistors in the converter. In addition, a constriction may be provided in a center leg of a transformer core of a switching transformer within the converter. To further improve efficiency, an RC acceleration element may be provided in a base circuit for the switching transistors.
